Definitions
- the invention relates to pneumatic control units with a control cylinder, which is equipped with signal or control contacts for contactless interrogation of the position of the control piston.
- the invention relates in particular to the control devices of the type mentioned, which are equipped with a control cylinder, on the outside of which controllable contacts, in particular so-called reed contacts or the like, are arranged magnetically or electronically by the piston of the control cylinder or parts connected to it which, as soon as the piston reaches a predetermined position, open electrical circuits or. shut down.
- Such reed contacts are usually housed in a housing which has guide elements with the aid of which it can be displaced in a guide on the outside of the cylinder in order to be able to adjust and adjust its position relative to the cylinder and thus to the movable control piston. It has proven effective to design such guides and guide elements as so-called dovetail guides, in which the dovetail-shaped guide elements of the reed contact housing can be inserted into adapted dovetail-shaped guide grooves from one of the two end faces of the control cylinder. As long as the control cylinder is equipped with only one contact there are no serious shortcomings with this type of training.
- the invention aims to provide a control cylinder for pneumatic control devices, primarily the design of the devices for holding and guiding the housing for a signal or interrogation contact, that is to say an embodiment which does not have such a defect and in particular a Inserting or replacing the housing in a dovetail guide groove of the control cylinder allows without changing the position of other control or signal contacts or. their housing becomes necessary.
- the cross-sectional area of the substantially trapezoidal guide rail of the contact housing has a shape that deviates from the trapezoidal cross-sectional area of the associated guide groove of the control cylinder which, with essentially the same height or depth of both elements (rail or groove), the width of the guide rail on the side adjacent to the contact housing is smaller than the gap width of the guide groove on its open side and in which the overall width of the guide rail is shortened to one dimension on one side is, which is determined by a circle around the one edge on the narrow side of the guide rail with a radius which is at the maximum equal to the gap width of the guide groove, the distance between the other edge on the narrow side of the guide rail from the diametrically opposite outer edge of the guide rail exceeds the width of the guide groove.
- the height of the guide rail should decrease towards the unabridged side of the guide rail.
- the inclination of the side surfaces of the guide rail can deviate from the inclination of the adjacent surfaces of the guide groove, in particular it can be reduced.
- the corresponding angle of the guide rail can be approximately 45 °.
- control cylinder is designated 11.
- An essentially dovetail-shaped groove 12 is provided in the control cylinder, the dimensions of which correspond to conventional grooves for the attachment of reed contact housings.
- the housing according to the invention can be inserted into this groove, so that an exchange of conventional housings for the ones according to the invention is possible and both types can optionally be used simultaneously.
- the contact housing shown as a blank in section for receiving a reed contact consists of an extruded section 13 with a substantially rectangular cross section and a threaded bore 131 for receiving an adjusting screw, not shown.
- the lower side 132 of the housing 13 in the drawing is designed as a dovetail-shaped guide rail with an essentially trapezoidal cross section. Shape and size of this trapezoid, that of conventional dovetail guides substantially match the shape and size of the associated cross-sectional area of the guide groove, in the present case deviate from the shape and size of the trapezoidal area of the cross-section of the groove 12 of the control cylinder 11.
- the dimensions of this holding and guide rail 132 are determined by the dimensions of the guide groove 12 on the cylinder 11.
- the width of the guide rail on the side adjoining the housing 13 must be smaller by a certain amount than the width of the gap 121 of the guide groove 12, in order for the guide rail of the contact housing to be inside the groove according to FIG To be able to slide side to side.
- the trapezoidal cross-section which is in principle trapezoidal, must be shortened on the one side to the extent specified by the radius 133, the radius 133 being allowed to reach the maximum of the width of the gap 121.
- the distance 134 which the one outer edge 135 of the guide rail 132 has from the diametrically opposite inner edge 136 of the guide rail 132 must be greater than the width of the gap 121 of the guide groove 12.
- the contact housing 13 is inserted into the groove 12 with the outer edge 135 of the guide rail first, it can be pivoted past the outer edge 121 of the guide groove 12 with the shortened part 137 of the guide rail until the guide rail 132 touches the bottom of the guide groove 12 creates. If the adjusting screw (not shown) seated in the bore 131 is then tightened, it is supported on the top or.
- the outer surface of the control cylinder and forces the outer edge 135 of the guide rail upward, whereby it moves upwards on the side wall 122 of the groove and thereby pushes the shortened part 137 under the side wall 123 of the groove 12.
